Project overview
WSDOT and design-build contractor Graham Contracting, Ltd. will construct a new on-ramp to northbound I-405 and a new off-ramp from southbound I-405 at Northeast 132nd Street in Kirkland. This type of interchange is known as a half-diamond. After this project is complete, travelers will have the option to access I-405 at Northeast 132nd Street, rather than traveling to the heavily congested Northeast 124th Street or Northeast 160th Street interchanges. The project design includes roundabouts at the intersections of the new ramps to better manage traffic flow. The design also includes sidewalk and bicycle lane enhancements along both sides of Northeast 132nd Street and along connecting streets in the project vicinity. The project also improves drainage, water quality and fish barrier correction to create over a half mile of new upstream fish habitat.
What to expect
Northeast 132nd Street on-ramp to northbound I-405 closed nights of Tuesday, May 21, Wednesday, May 29, and Thursday, May 30
Crews will close the Northeast 132nd Street on-ramp to northbound I-405 later this month to install electrical elements and permanent lighting. The closures will take place from approximately 9 p.m. to 5 a.m. on the following days:
- Tuesday, May 21
- Wednesday, May 29
- Thursday, May 30
During these closures, a signed detour will direct travelers to use the on-ramp to northbound I-405 at Northeast 124th Street.
I-405/SR 167 Program celebrates completion of one project and start of another
Finishing one project and starting another was cause for a pair of celebrations today showcasing progress toward delivering on our multimodal vision of the I-405/SR 167 Corridor Program.
Agency and elected officials, corridor partners, community members, contractors and project teams gathered to mark the start of construction for the I-405/Brickyard to SR 527 Improvement Project in Bothell and the completion of the I-405/Northeast 132nd Street Interchange Project in Kirkland.
The I-405/Brickyard to SR 527 Improvement Project broke ground with a ceremonial turning of the dirt at the Brickyard Park & Ride. WSDOT, Sound Transit, and design-build contractor, Skanska USA Inc., are working together to enhance four and a half miles of the corridor from just south of SR 522 to SR 527. When complete in 2028, the project will extend the dual-express toll lane system on the north end of I-405, add three new Sound Transit bus rapid transit stations, and improve multimodal connections to the corridor.
Following the groundbreaking ceremony, we held a ribbon cutting ceremony at Kingsgate Park & Ride to mark the completion of the I-405/Northeast 132nd Street Interchange Project. We celebrated the new on- and off-ramps to I-405 at Northeast 132nd Street, as well as the newly constructed roundabouts, improvements for bicyclists and pedestrians, and the newly established fish passage.
The project includes roundabouts at the intersections of the new ramps and Northeast 132nd Street.
